Biotin-PEG3-azide is a PEGylated version of biotin-azide (Item No. 13040) that is more hydrophilic due to the incorporation of a PEGylated spacer. It can be used to label terminal alkynes via copper-catalyzed click reactions or copper-free click reactions with cyclooctynes.1,2 Biotin-PEG3-azide has been used to non-enzymatically and covalently tag proteins, which can be separated and detected using common laboratory methods such as SDS-PAGE and Western blot.3 It can be used in combination with other protein tags. Biotin-PEG3-azide has also been used in nanostructured biointerfaces to study ligand and receptor spacing when there are different signaling molecules present.1
